摘　　要：在缺氧状态下快速加热中药渣,然后迅速冷却为液体生物油;在气体中的高分子化合物完全分解前进行中温浓缩,以减少气体产物的形成,提高液相产物产量;再通过脱水分离为木醋酸和木焦油。木醋酸经减压分馏获得乙酸、丙酸、丁酸、甲醇和其它有机溶剂,木焦油可加工为杂酚等抗聚剂,提高了中药渣附加值。In this article, medicine herb residue was rapidly heated in the hypoxic state, turned into liquid bio-oil by rapidly cooling, and then condensed by gaseous high molecular compound in medium baking temperature before complete decomposition, so that the formation of gas products was decreased, and liquid products was increased, thereafter wood vinegar was and tar were separated by dehydration. The wood vinegar was transformed into acetic acid, metacetonic acid, butyric acid, methanol and other organic solvents, and the tar was processed into deflocculation agent,such as creosote, so medicine herb residue＇ added value was increased.
